7th-Grader Designs Three Dimensional Solar Cell

This just in from the really, really future scientists of America via Slashdot..."12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light
has won him an award and a $25,000 scholarship from the Davidson
Institute for Talent Development. 'Current solar cells are flat and can
only absorb visible light'" Yuan said. 'I came up with an innovative
solar cell that absorbs both visible and UV light. Solar panels with his 3D cells would provide 500 times more light absorption
than commercially-available solar cells and nine times more than
cutting-edge 3D solar cells. 'My next step is to talk to manufacturers
to see if they will build a working prototype,' Yuan said. "If the
design works in a real test stage, I want to find a company to
manufacture and market it.""

Single-walled nanotubes are an important variety of carbon nanotube because they exhibit electric properties that are not shared by the multi-walled carbon nanotube (MWNT) variants. Single-walled nanotubes are the most likely candidate for miniaturizing electronics beyond the micro electromechanical scale currently used in electronics. The most basic building block of these systems is the electric wire, and SWNTs can be excellent conductors. One useful application of SWNTs is in the development of the first intramolecular field effect transistors (FET). Production of the first intramolecular logic gate using SWNT FETs has recently become possible as well.
